Question 1

True or false?

One of the angles in a rectangle may be an acute angle.

Question 2

True or false?

The sum of two acute angles can be greater than 180 degrees?

Question 3

Does the drawing show an adjacent angle?

Question 4

Does the drawing show an adjacent angle?

Question 5

Choose the appropriate triangle according to the following:

Angle B equals 90 degrees.

True or false?

One of the angles in a rectangle may be an acute angle.

One of the properties of a rectangle is that all its angles are right angles.

Therefore, it is not possible for an angle to be acute, that is, less than 90 degrees.
